But here's the good news: There's a simple step you can add to your nighttime routine to keep you safe. Research from UL's Firefighter Safety Research Institute (FRSI) shows that closing your bedroom door helps prevent a fire from spreading, lessens smoke damage and could even save lives.
Closing your bedroom door before you go to sleep will substantially improve your chances of surviving a fire in your home. According to the National Fire Protection Association (NFPA), the number of home fires decreases when people go to sleep.
Those who slept with the bedroom door open reported a better and longer night's sleep than those who slept with the door closed.
The answer to this is yes, since it can limit air circulation in your home and require less rooms to be cooled or heated. However, air can still seep under closed doors, so it won't keep your rooms the same temperature for long.
To Prevent Other Break-ins
So, it's very important that you not only make sure your door is locked at night, but also adding some extra security to your door, such as a door chain.
Positioning your bed in line with the door is the worst possible position, according to the principles of Feng shui. People who practice Feng shui call it the 'dead man's position' or the 'coffin position' because the feet or head face the door and resemble how we carry the dead through open doors from the house.
Never Let your Bed Face a Door
Feng Shui experts explain that your bed facing a door (be it the main bedroom door or a balcony door) is bad luck because the door will “pull” your energy away from you as you sleep.
Heat intake during these nights comes from things like wind blowing into windows or cracks beneath doors (wind speeds increase significantly at night), warm air passing by your skin (air temperatures are typically higher nearer to the ground), and hot objects within rooms like lights, electronics, appliances (some ...
Closed, poorly ventilated spaces often have carbon dioxide levels greater than 1000 parts per million. Headaches, impaired mental function, lethargy, and even reduced school attendance have all been linked to high carbon dioxide concentrations that many people are exposed to in their daily lives for hours at a time.
According to a recent survey by the safety science organization Underwriters Laboratories, nearly 60% of people sleep with their bedroom door open.
Research suggests that wearing socks to bed can help people not only fall asleep faster, but sleep longer and wake up fewer times throughout the night. One study found that young men wearing socks fell asleep 7.5 minutes faster, slept 32 minutes longer, and woke up 7.5 times less often than those not wearing socks.
In a recent study, Canha and colleagues found that closed doors and windows led to higher levels of carbon dioxide, carbon monoxide and other substances such as formaldehyde.
It boosts your metabolism
Sleeping in a cold room helps to boost your metabolic process, which in turn helps to lower the risk of suffering from diseases such as high blood pressure and diabetes. It also boosts the production of growth hormones which help to repair damaged muscle tissues and bone fractures.
A cold sleeping environment helps lower your body temperature, making it easier to experience deep sleep. This is why you usually feel well-rested after sleeping in a cold room. Plus, lower temperatures help with melatonin production and better sleep quality.
Ceiling fans circulate air in the room by pushing it down. However, they can not lower the temperature like a window fan or AC unit. But they can still cool you down. That's because their breeze creates a slight wind chill effect that can help sweat evaporate from your skin, which cools you down.
Hormones
Imbalances in your hormone levels can lead to night sweats or hot flashes. Many females experience night sweats as part of premenstrual syndrome due to fluctuations in estrogen and progesterone levels. Night sweats and hot flashes are two of the most common symptoms of menopause.
If you catch yourself or other movements in the reflection it can be difficult for the brain to switch off and go to sleep. This can cause problems like “sleep paralysis” (also known as a hypnagogic hallucination), a condition which causes sufferers to feel as though they are between a sleeping and waking state.
According to Vastu, the right direction of the bedroom should be the south-west corner of the house. The ideal bed direction as per Vastu is with the head towards the south or east so that the legs are towards north or west direction while sleeping.
According to ancient traditions like vastu shastra, the best direction to sleep in is toward the south. This theory is also supported by some recent research . This means that when you lie in bed, your head is pointed south , and your feet are pointed north.
If you stick out your feet out of your blanket in the winter season then it might make you feel cold and you might have to get the feet back inside your blankets, this can eventually lead to disturbance in sleep.
What you should avoid instead is placing your sleeping quarters in bad positions for Feng Shui, such as North, North East and South. North: North can increase various sleep disorders such as insomnia and make you rather lethargic in your life. This position is often called the 'death position'.
Most people avoid the bed under the window at all costs. Further, feng shui rules warn against it as too much energy flows out of the room causing restless sleep. Even traditional designers discourage the positioning of a bed in front of the windows.
Simply put, humans don't take in as much oxygen as we think we do. Based on oxygen alone, estimates are that the average person could survive in a completely sealed, airtight room for 12 full days! Running out of oxygen in a room is quite unlikely.
